News about President Donald Trump’s alleged affairs have captured the national attention as a porn star and a playboy model offer to publicly describe their experiences with the President before he came to office.

Trump has denied the encounters with Stormy Daniels and Karen McDougal ever took place, but many have found the women’s accounts convincing. And if Trump did cheat on his wife before he was elected president, he wouldn’t be the first president to do so.

Historians say numerous presidents probably had affairs before and during their presidency. These are a few examples:

The letter was a flirty note to Sally Fairfax, the wife of Washington’s longtime friend and neighbor George Fairfax, and was written when Washington was already engaged to his future wife Martha. Washington and Sally Fairfax were known to be close and to have performed in amateur theater together while living in Virginia. After Washington married, Sally moved back to England and kept the letter in her possession until her death.

Woodrow Wilson (1913-1921)

For eight years, seven of which he was married, Woodrow Wilson maintained constant communication with a women he had met while vacationing in Bermuda.

Wilson had traveled alone to Bermuda in the winter of 1907, where he met Mary Hulbert Peck. He returned the next year to visit her again. When he wasn’t traveling to see her, Wilson wrote Peck over 200 letters in which he called her “my precious one” and “my beloved.”

Wilson’s wife was allegedly aware of the relationship and encouraged it because she was experiencing depression.

Franklin Delano Roosevelt (1933-1945)

Roosevelt, who married his distant cousin Eleanor, later went on to allegedly have an affair with her secretary Lucy Mercer. Eleanor later discovered love letters between Mercer and her husband in 1918, long before he was President.

The couple stayed together, but they allegedly slept in separate beds. Roosevelt also broke his promise to his wife that he would stop seeing Mercer. The mistress was there the day Roosevelt died while his wife was not.

John F. Kennedy (1961-1963)

John Kennedy was a notorious playboy whose extramarital affairs were so numerous that this shouldn't be a surprise. Among the most famous were his affairs with the movie star Marilyn Monroe, 19-year-old White House intern Mimi Alford, and Los Angeles socialite Judith Exner.

Bill Clinton (1993-2001)

Rumors of Bill Clinton’s affairs spread during his campaigns for office and long political career, but it wasn’t until he was in the presidency that the now well-known Lewinsky affair evolved into a full-blown scandal. The affair consumed the media in the late 1990s.
